实施例一
本发明实施例一提供一种话权信息的通知方法,该方法可以应用 于基于 LTE 的宽带集群通信***中, 且在网络侧通过多小区联合传 输方式为 UE提供组呼会话服务时, 用于将组呼会话相关的话权指示 信息从核心网设备发送到接入网设备,并由接入网设备将话权指示信 息发送给 UE ,以满足宽带集群通信***中话权指示信息派发的需求, 如图 2所示, 该方法包括以下步骤:
步骤 201 , 核心网设备获得针对特定组呼会话的话权指示信息;
其中, 该核心网设备可以包括但不限于 ΜΜΕ。
步骤 202, 核心网设备将针对特定组呼会话的话权指示信息通知 给 MCE。
本发明实施例中, 为了将话权指示信息通知给 MCE, 在 M3接 口上需要对话权指示信息的通知信令以及通知信令中携带的信息进 行设计; 而且考虑到核心网设备在将话权指示信息发送给 MCE 时, 核心网设备与 MCE之间承载 M3接口的传输网不能保证通知信令的 按序到达, 一旦话权指示信息的通知信令存在乱序的情况, 则将会导 致集群 UE保存的话权状态出现错误, 因此需要避免话权指示信息的 通知信令出现乱序的情况。
基于上述考虑,核心网设备将针对特定组呼会话的话权指示信息 通知给 MCE包括: 核心网设备通过组呼会话相关的 M3AP ( M3接 口应用层) 消息将针对特定组呼会话的话权指示信息通知给 MCE; 或, 核心网设备通过非组呼会话相关的 M3AP 消息将针对特定组呼 会话的话权指示信息通知给 MCE。
方式一, 核心网设备通过组呼会话相关的 M3AP 消息将针对特 定组呼会话的话权指示信息通知给 MCE。
本发明实施例中,该组呼会话相关的 M3AP消息包括但不限于: Speaking Right Indication (话权指示) 消息; 且该 Speaking Right Indication 消息中至少携带 MME MBMS M3AP ID、 MCE MBMS M3AP ID、 TGID、 Speaking Right; 该 MME MBMS M3AP ID表示在 组呼会话建立过程中, 由核心网设备为组呼会话分配的临时标识; 该
MCE MBMS M3AP ID表示在组呼会话建立过程中, 由 MCE为组呼 会话分配的临时标识;该 TGID表示群组的 NAS( Non Access Stratum, 非接入层)层标识;该 Speaking Right表示当前群组的话权占用情况, 且该话权占用情况具体包括占用和空闲两种状态。
如表 1所示, 为一种 Speaking Right Indication消息的格式示例。 表 1
进一步的, 在核心网设备通过组呼会话相关的 M3AP 消息将针 对特定组呼会话的话权指示信息通知给 MCE后, 且核心网设备在接 收到来自 MCE的组呼会话相关的 M3AP消息的响应消息之前,核心 网设备不会发起针对同一组呼会话的话权指示过程 (即拒绝发送针对 同一组呼会话的话权指示信息)。
本发明实施例中, 该组呼会话相关的 M3AP 消息的响应消息包 替 ( 第 26条)
括但不限于: Speaking Right Response (话权响应)消息;且该 Speaking Right Response 消息中至少携带 MME MBMS M3AP ID 和 MCE MBMS M3AP ID; 且该 MME MBMS M3AP ID表示在组呼会话建立 过程中, 由核心网设备为组呼会话分配的临时标识; 该 MCE MBMS M3AP ID表示在组呼会话建立过程中, 由 MCE为组呼会话分配的临 时标识。
如表 2所示, 为一种 Speaking Right Response消息的格式示例。 表 2
需要注意的是, 对于 Speaking Right Indication和 Speaking Right
Response, 其中组呼会话本身通过 MME MBMS M3AP ID和 MCE MBMS M3AP ID进行标识 ,且 MME MBMS M3AP ID和 MCE MBMS M3AP ID是在组呼会话建立过程中, 分别由 MME和 MCE为组呼会 话分配的临时标识。
方式二, 核心网设备通过非组呼会话相关的 M3AP 消息将针对
特定组呼会话的话权指示信息通知给 MCE。
本发明实施例中, 该非组呼会话相关的 M3AP 消息包括但不限 于: Speaking Right Notification (话权通知 )消息;且该 Speaking Right Notification消息中至少携带 TGID和 Speaking Right; 且该 TGID表 示群组的 NAS层标识; 该 Speaking Right表示当前群组的话权占用 情况, 且该话权占用情况具体包括占用和空闲两种状态。
如表 3所示,为一种 Speaking Right Notification消息的格式示例。 表 3
需要注意的是, 在核心网设备通过非组呼会话相关的 M3AP 消 息将针对特定组呼会话的话权指示信息通知给 MCE (即核心网设备 在发送 Speaking Right Notification 消息)之前, 还需要启动定时器 TimeO, 且在定时器 TimeO超时之前不再发送针对具有相同 TGID标 识的群组的新的话权指示信息(即拒绝发送针对具有相同 TGID的群 组的新的话权指示信息); 进一步的, 该定时器 TimeO设定的时间间 隔需要够长,以保证核心网设备后发送的话权指示信息不会在前一条
话权指示信息之前到达 MCE。
步骤 203 , MCE接收来自核心网设备的针对特定组呼会话的话 权指示信息。 本发明实施例中, MCE接收来自核心网设备的针对特 定组呼会话的话权指示信息包括: MCE接收来自核心网设备的携带 针对特定组呼会话的话权指示信息的组呼会话相关的 M3AP 消息; 或者, MCE接收来自核心网设备的携带针对特定组呼会话的话权指 示信息的非组呼会话相关的 M3AP消息。
该组呼会话相关的 M3AP 消息包括但不限于: Speaking Right Indication消息,且该 Speaking Right Indication消息中至少携带 MME MBMS M3AP ID, MCE MBMS M3AP ID、 TGID、 Speaking Right; 该非组呼会话相关的 M3AP 消息包括但不限于: Speaking Right Notification消息, 且该 Speaking Right Notification消息中至少携带 TGID以及 Speaking Right。
需要注意的是, MCE在接收到来自核心网设备的组呼会话相关 的 M3AP消息之后, 该 MCE还需要向核心网设备发送组呼会话相关 的 M3 AP消息的响应消息, 且该组呼会话相关的 M3 AP消息的响应 消息包括但不限于: Speaking Right Response 消息; 且该 Speaking Right Response 消息中至少携带 MME MBMS M3AP ID 和 MCE MBMS M3AP ID。
步骤 204, MCE将针对特定组呼会话的话权指示信息通知给接 入网设备。
本发明实施例中, 为了将话权指示信息通知给接入网设备, 在
M2接口上需要对话权指示信息的通知信令以及通知信令中携带的信 息进行设计; 基于上述考虑, MCE将针对特定组呼会话的话权指示 信息通知给接入网设备包括: MCE在一个 MCCH ( Multipoint Control Channel, 多播控制信道) 消息更新周期内, 将从核心网设备收到的 针对不同组呼会话或不同群组的话权指示信息进行合并,生成包含针 对特定组呼会话的话权指示信息的话权信息列表,并通过非组呼会话 相关的消息将话权信息列表通知给接入网设备 (如 eNB )。
本发明实施例中, 该非组呼会话相关的消息包括但不限于: Speaking Right Indication消息; 且该 Speaking Right Indication消息中 至少携带 MCCH Update Time、 MBSFN Area ID、 SpeakingRightList; 该 MCCH Update Time表示话权指示信息在 MCCH信道上进行发送 的时间; 该 MBSFN Area ID表示进行话权指示信息发送的 MBSFN 区域标识; 该 SpeakingRightList 为话权信息列表, 且该 SpeakingRightList中的每个信息项用于指示特定群组的 NAS层标识 (群组信息使用 TGID标识 )以及当前群组的话权占用情况(话权状 态情况使用 speakingRight进行标识), 且该话权占用情况具体包括占 用和空闲两种状态。
如表 4所示, 为一种 Speaking Right Indication消息的格式示例。 表 4
步骤 205, 接入网设备接收来自 MCE的针对特定组呼会话的话 权指示信息。 本发明实施例中, 接入网设备接收来自 MCE的针对特 定组呼会话的话权指示信息具体包括: 接入网设备接收 MCE在一个 MCCH 消息更新周期内发送的携带话权信息列表的非组呼会话相关 的消息,且该话权信息列表中至少包含针对特定组呼会话的话权指示 信息; 该非组呼会话相关的消息包括但不限于: Speaking Right
Indication消息;且该 Speaking Right Indication消息中至少携带 MCCH Update Time、 MBSFN Area ID, SpeakingRightList。
需要注意的是, 接入网设备在接收到来自 MCE的针对特定组呼 会话的话权指示信息后, 还需要向 MCE返回针对非组呼会话相关的 消息(如 Speaking Right Indication消息)的响应消息, 且该响应消息 包括但不限于 Speaking Right Response;如表 5所示,为一种 Speaking Right Response消息的格式示例。
表 5
步骤 206, 接入网设备将针对特定组呼会话的话权指示信息通知 给参与特定组呼的所有被呼 UE。
本发明实施例中,非组呼会话相关的消息中携带话权指示信息在 MCCH信道上进行发送的时间以及话权信息列表; 且接入网设备将 针对特定组呼会话的话权指示信息通知给参与特定组呼的所有被呼 UE包括:接入网设备根据话权指示信息在 MCCH信道上进行发送的 时间(即 MCCH发生更新的时刻 )将话权信息列表通过 MCCH信道 在空口进行发送,以将针对特定组呼会话的话权指示信息通知给参与 特定组呼的所有被呼 UE。
综上所述, 本发明实施例中, 核心网设备通过 MCE将针对特定
组呼会话的话权指示信息发送到接入网设备,并由接入网设备将针对 特定组呼会话的话权指示信息发送给特定群组的 UE, 从而将特定组 呼的话权指示信息通知参与组呼的所有被呼 UE, 使特定群组的 UE 通过发起话权抢占的方式抢占话权。
